STAI 1-8-45 FU-I

STAI operators are robust commercial door operators with an overhead track. They offer the optimal operator solution for spring-balanced sectional doors with low lintel fittings or lack of lateral space for installation. Due to their robust design, they are equally well suited for use in underground garages. Gates with a maximum height of 4,500 mm can be automated. The gearmotors are based on the proven STA operators. All STAI series operators operate on the basis of an external control system; special solutions for individual customer requirements can be implemented flexibly and quickly at any time.

STAI 1-8-45 FU-I

Features:

  • Die-cast aluminum housing, rolled worm shaft and double worm shaft bearings
  • Emergency operation via unlocking mechanism on the guide carriage of the operator rail
  • Supply: 230/400 V/3~/50 Hz
  • Thermal protection in the motor winding
  • For gate systems with above-average circuits, a operator with an increased motor duty cycle (HD) should be selected
  • Pluggable connectors
  • End position setting via electronic absolute encoder (AWG) or mechanical limit switches (MEC)
  • Version with external control, can be combined with extensive control program. Supply: 230/400 V/3~, frequency: 50/60 Hz and control voltage: 24 V-DC
  • When the output speed is increased (operation with frequency converter), the output torque is reduced. In this case, the following applies: An increase of the output speed by 10 % causes a reduction of the output torque by 5 %.
  • The soft-start and soft-stop technology ensures a longer service life of the door system, as the door mechanism is subjected to less stress. This reduces repair costs.
  • Special variants such as further voltages and frequencies, output speeds and higher degrees of protection on request
  • Mounting and installation components available
  • For temperature ranges below -20 °C there is suitable oil and electric heating on request
